Hi Marc,
this is a trimmed down version of the previous series. All irq_sim patches from the previous implementation were dropped. The only change in irq_sim now is addition of the irq_sim_get_type() helper. We store the irq type in the irq_set_type() callback and allow users to retrieve it with the new function.
The entire logic handling the line state now lives directly in the only user that needs it - the GPIO testing module. Since the GPIO user API only supports edge interrupts, level types are not supported. This functionality is only needed for user-space tests. The testing module tracks the line state and makes sure to avoid impossible situations (like firing a rising edge interrupt if the line is being driven low).
Other gpio-mockup patches are unchanged - the only change in patch 7 is the line state tracking.
v1 -> v2: - instead of providing the irq_sim_get_type() helper, move the irq type logic into the simulator and provide a helper that allows users to specify the type of the fired interrupt
v2 -> v3: - switch back to having irq_sim_type() and put the line state logic into the GPIO testing module
Bartosz Golaszewski (7): irq/irq_sim: provide irq_sim_get_type() gpio: mockup: add locking gpio: mockup: implement get_multiple() gpio: mockup: don't create the debugfs link named after the label gpio: mockup: change the type of 'offset' to unsigned int gpio: mockup: change the signature of unlocked get/set helpers gpio: mockup: rework debugfs interface
